  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here!

Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area.

    Hello from Toronto!

    You gave me and my kids a viewing of your casting and I was hooked! I may have helped you with your home too…unless of course someone stole your handle/name…

    CA-ON Bentone 34 or other “organophilic” clay?

    I’m interested too. Which supplier did you get it from? @Tobho Mott is looking for some too. I’ve only played with a small sample qty. and used it to rejuvenate my petrobond. To be honest @Ogmios Forge I’d be more worried about the fumes coming of the k-Bond or Petrobond. I’m about ready to...

    Hello from Toronto!

    Great to see you here! I hold you entirely responsible for getting me hooked on casting bronze and the change in trajectory my work has taken. Thank you, seriously. As for the Bentone let’s talk. It’s been a while since I checked but there are a few places and it might be that a group buy might...

    Best Product to Use for Fillets and Curves in a Simple Aluminum Pattern

    I second the JB weld idea, except I use Oatey fixit stick in the plumbing section. At $10 for a big stick it works well. It’s. Putty you cut off what you need, knead it, and it sets faster than most of the JB weld stuff. Probably because it has a lot of BPA in it…it sets quick and sands/machines...

    Hot rolled and pickled

    Has anyone tried citric acid for mill scale? I did use the hydrochloric/muriatoc acid with a neutralizing bath after but a bit of a pain.

    Mr Metal often had P&O in Toronto. Nice not to have the mill scale.

    CA-ON Multi-conductor wire

    I’m up in Brampton if you want to come and get it.

    CA-ON Multi-conductor wire

    I would take a length of flexible conduit (liquid tight, armoured, or similar) and pass individual stranded wires, often called “pull wires” at the supplier. You can buy both at Home Depot. The wires will be in little spools in different colours or you can get them to sell you it off the big...

    molten metal temp

    I made a similar setup using a cheap handheld thermocouple reader <$40 and the temperature probe (Mifco type) I got from Foundry Supply Source (used to be Smelko). I'll find a picture of the "temporary prototype" that became permanent.

    Novakon NM-200 upgrade from mach3

    No tool changer unfortunately.

    Novakon NM-200 upgrade from mach3

    Thanks so much for the link to the tutorial! I've seen so many threads and most of them end up with some problem or another. Is the 1100-3 the closest to the Novakon nm-200 Series 1 with steppers. Thanks!

    Novakon NM-200 upgrade from mach3

    No problems buying the stick from Studica for me either. Now with a pair of 7i92T's time to get at transitioning my mill and a Emco 5 CNC from Mach...any tips?

    Tips/Techniques 3DP Post Processing

    Graphite so it pulls nice from the sand(petrobond) for casting. Eliminates having to shellac or clear coat. Especially good if it’s just a trial casting.

    Tips/Techniques 3DP Post Processing

    I use Dynapatch Pro (Home Depot) as a filler on PLA. Stock quite well. Sand and Graphite after. Not the strongest durability wise but it doesn’t stink, is quick and works fine for sand casting. Will definitely try the UV resin, but I’m sure I need some better ventilation for that… Polysmooth...
